	re-create the table of contents here, because it will replace the
9 
	hand-edited TOC subheads with a separate subhead for each H2 in
10 
	the body of the file.  Or if you do, first look at the original
11 
	TOC to see how to edit it for visual conciseness.

Remove the bmpa*** devices from the default build. These are example devices
346 
to demonstrate async rendering but do not have any advantages to users over
347 
the bmp*** devices, and their inclusion requires thread support which is not
348

1146 
NOINTERPOLATE flags. These flags had no effect on PDF because the PDF
1147 
interpreter is bound earlier than image operator is redefined. New version

	- Allocate filter in local VM when currentglobal is false. Prevents
1160 
a problem with some QuarkXpress ProcSets that turn off vmreclaim and expect
1161 
save/restore to free memory which only works on local VM. Fix for problem

reported by Artifex customer #150, file "japan.ps". (zfilter.c [1.5]:

1164 
	- Speed-up JPEG decompression by increasing file buffer to 2K. This
1165 
avoids installation of an intermediate buffering filter that resulted in a
1166 
byte-by-byte filling of the buffer to the JPEG code. When the buffer was not
1167 
full enough a recoverable error would result in a round trip for the next

This long-overdue fileset includes major new developer documentation, major
1581 
improvements in the PDF writer (for embedded fonts and for DSC comments),
1582 
and lots of bug fixes.  Unfortunately, for unknown reasons, the release
1583 
"smoke test" loops forever on the file data/ps/screen.ps -- but only when
1584 
compiled in 'production' mode, not in 'debug' mode.  We suspect a gcc bug,

but don't have the time to track it down before the end of the millennium.

special charaters. also enable '-r' commandline option, and pass '-b' if
1801 
it's not specified for default branch logs only. Changes.htm now passes the

(devs.mak [1.40]: 2000/12/10 00:17:51 lpd)
1813 
	- Seek was broken and PDF interpreter failed when

Adds DSC parsing capability to the PostScript interpreter, with an optional

Adds the 'hook' for passing DSC comments to the PDF writer, but doesn't
1837 
actually process any of the comments. NOTE: Part of this code was
1838 
accidentally included in the recent fix for local/global VM problems in the

Avoids exporting empty LD_RUN_PATH environment variable to the link process.

This was causing binaries to search the current directory for libraries,
1847 
which was a security hole. Fixes SourceForge bug 122532. (ugcclib.mak [1.6],

Extensively revises and updates the pdfwrite text handling code to support
1856 
processing and embedding of all types of fonts (except for Type 3 and
1857 
CIDFontType 1, which are defined by PostScript procedures), and all variants
1858

1868 
 
1869 
Adds a '-t' option to enable text output rather than html, replacing the old
1870 
behavior, which was to return text unless a version string was passed with
1871 
'-v'. The version string is now set to 'CVS' if no explicit version is
1872 
passed, and this is used in the named anchors within the html output.

1969 
	- If the same standard (base 14) font was loaded more than once

The published PDF specification says the Encoding name "must be" one of the

3 predefined Encodings, implying that an error should occur if it isn't.

However, Acrobat Reader simply ignores unknown names, and since there are

The PDF specification says that the 'xref' must be on a line by itself. The

valid but exceeded the maximum stack depth, an attempt was made to free a

	- Disk-based TrueType fonts caused a memory leak. (Currently, there
2102 
are no such fonts, but CIDFontType 2 fonts, and directly-accessed TrueType
2103 
fonts, should be made disk-based.) (zfcid1.c [1.4]: 2000/11/22 08:32:07 lpd)
2104 
	- Type 1 CharStrings loaded from disk for type 0 CIDFonts were never
2105 
freed, except by garbage collection (which doesn't reclaim chunks with only
2106 
a small amount of surviving data). In practice, this probably only affects
2107 
the PDF writer. (zfcid0.c [1.5]: 2000/11/23 23:34:22 lpd)
2108

	- 'gstate' was allowed in global VM even if the current graphics
2120 
state included references to structures in local VM (which is, in fact,
2121 
normally the case) and the save level was non-zero: this could create a

Fixes problems:
2261 
	- Several places in the band list code didn't call s_init_state to
2262 
initialize locally allocated stream states: this is now required (see the
2263 
"Incompatible changes" section above). We suspect there are a few more
2264 
places that will need this fix. (gxclbits.c [1.3], gxcldev.h [1.4],
2265 
gxclread.c [1.3], gxclutil.c [1.3]: 2000/11/05 00:34:24 lpd)
2266 
	- Fixes infinite loops when writing large bitmaps into clist. Now,
2267 
cmd_put_bits never requests an allocation in the clist buffer larger than
2268 
cbuf_size. (gxclbits.c [1.4]: 2000/11/05 18:44:57 raph)
2269 
	- Works around an Acrobat Reader 4 bug that causes AR4 to draw a
2270 
single pixel, rather than nothing, when filling a subpath consisting only of
2271 
a moveto. (gdevvec.c [1.8]: 2000/11/07 16:42:28 lpd)
2272 
	- The PDF writer didn't handle stroked fonts correctly (they were
2273 
filled instead of stroked). (gdevvec.c [1.9], gdevvec.h [1.5]: 2000/11/12
2274 
06:52:08 lpd)
2275 
	- The pdfwrite and pswrite drivers could emit a lineto or rlineto
2276 
without a moveto at the beginning of the path. (bug introduced very
2277 
recently, by a workaround for an Acrobat Reader bug) (gdevvec.c [1.10]:
2278 
2000/11/14 07:41:08 lpd)
2279 
	- Attempting to write a CFF Type 2 font larger than 32K but smaller
2280 
than 64K caused a rangecheck. (gdevpsf2.c [1.8]: 2000/11/19 17:48:08 lpd)
2281 
	- Computing the default width or the fixed width for a CIDFont or
2282 
TrueType font could do a huge amount of unnecessary work. (Probably only
2283 
affects the PDF writer.) (gsfont.c [1.3]: 2000/11/20 21:09:09 lpd)
2284 
	- The Type 1 to Type 2 CharString converter (currently used only by
2285 
the PDF writer) often didn't detect invalid CharStrings as input.
2286 
(gdevpsfx.c [1.6]: 2000/11/21 02:33:55 lpd)
2287 
	- The code for writing a CIDFontType0 CFF font mistook Type 2
2288 
CharStrings for Type 1, and tried to convert them to Type 2. (This currently
2289 
affects only the PDF writer.) (gdevpsf2.c [1.9]: 2000/11/21 02:35:59 lpd)
2290 
	- Disk-based TrueType fonts caused a memory leak. (Currently, there
2291 
are no such fonts, but CIDFontType 2 fonts, and directly-accessed TrueType
2292 
fonts, should be made disk-based.) (gdevpsft.c [1.5], gstype42.c [1.10]:
2293 
2000/11/22 08:32:07 lpd)
2294 
	- Type 1 CharStrings loaded from disk for type 0 CIDFonts were never
2295 
freed, except by garbage collection (which doesn't reclaim chunks with only
2296 
a small amount of surviving data). In practice, this probably only affects
2297 
the PDF writer. (gsfcid.c [1.5], gstype1.c [1.6], gstype2.c [1.9],
2298 
gxfont1.h [1.5], gxtype1.c [1.8], gxtype1.h [1.5]: 2000/11/23 23:34:22 lpd)
2299 
	- The pswrite device couldn't write to pipes. The fix involved
2300 
expanding the API for opening device OutputFiles so that the individual
2301 
driver could specify whether it required, requested, or did not want a
2302 
positionable file. Fixes SourceForge bug # 122223. (gdevpipe.c [1.4],
2303 
gdevvec.c [1.11], gdevvec.h [1.6], gsdevice.c [1.8]: 2000/11/29 02:25:13
2304 
lpd)
2305 
	- The change for freeing transient CharStrings introduced two bugs,
2306 
possibly causing the code to free data twice, or to free data that should be
2307 
retained. (gdevpsfx.c [1.8]: 2000/11/30 05:58:19 lpd)
2308 
	- Allocates graphics state path in stable memory. This prevents
2309 
paths in Type 3 fonts allocated inside a save ... setcachedevice ... restore
2310 
sequence from being prematurely freed. Fixes SourceForge bug 101549.
2311 
(gspath1.c [1.3], gsstate.c [1.6]: 2000/12/04 21:13:55 raph)
2312 
	- An inadvertent change caused the graphics state not to be freed on
2313 
grestore. This fix, due to lpd, restores the freeing statement.
2314 
(gsstate.c [1.7]: 2000/12/05 09:24:57 raph)
2315 
	- The pointers to the substituted color spaces in the graphics state
2316 
weren't included in the structure descriptor, causing memory access errors
2317 
if UseCIEColor was used. (gsstate.c [1.8]: 2000/12/11 04:06:22 alexcher)
2318 
	- In TrueType fonts, glyph outlines starting with an off-curve point
2319 
didn't render correctly, replacing the curve with a pair of straight lines.
2320 
(gstype42.c [1.11]: 2000/12/12 22:27:56 alexcher)

2328 
	- Fixes a subtle logic bug in the scan line path filling code, which
2329 
unfortunately involved rewriting the code from scratch. The new code is also
2330 
somewhat subtle, and may contain new bugs: DON'T TRUST IT YET. Fixes
2331 
SourceForge bug # 117066. (gxfill.c [1.7]: 2000/12/23 06:02:39 lpd)
2332 
	- Embedded Type 1 fonts omitted StdVW. (Acrobat Reader requires
2333 
this, even though the Type 1 specification says it is optional.)

2348 
16:46:55 lpd)
2349 
 
2350 
Adds a procedure for testing whether a glyph is a "notdef" in a font,
2351 
necessary for fixing a memory consumption problem when accessing type 0
2352 
CIDFonts. (gsfont.c [1.4], gxfont.h [1.3]: 2000/11/23 23:23:40 lpd)

2357 
 
2358 
Improves the performance of embedded font writing by freeing strings when no

14:41:34 igorm)
2378 
 
2379 
Adds macros for suffix subclass structures with 7 or 8 additional pointers
2380 
(1-6 and 9 existed already). (gsstruct.h [1.7]: 2000/12/04 01:11:53 lpd)
2381 
 
2382 
Extensively revises and updates the pdfwrite text handling code to support
2383 
processing and embedding of all types of fonts (except for Type 3 and
2384 
CIDFontType 1, which are defined by PostScript procedures), and all variants

2386 
all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both

Fixes problems:
2596 
	- The PostScript image writing drivers (psmono/gray/rgb) didn't set
2597 
the page size in the output, and didn't produce DSC-compliant output.
2598 
(devs.mak [1.31]: 2000/08/09 06:55:45 lpd)
2599 
	- The FlateEncode and zlibEncode filters didn't implement the
2600 
"Effort" parameter. (fix from Alex Cherepanov) (int.mak [1.28]: 2000/08/09
2601 
16:55:24 lpd)
2602 
	- Because "-" as an OutputFile now references the %stdout IODevice,
2603 
it no longer worked in configurations without a PostScript interpreter.
2604 
Fixing this required factoring out the stdin/out/err IODevices and providing
2605 
an implementation that didn't reference the PostScript interpreter.
2606 
(int.mak [1.32], lib.mak [1.34], ugcclib.mak [1.3]: 2000/09/07 06:14:45 lpd)
2607 
	- Configurations including PDF but not PostScript didn't include all
2608 
the PostScript LL3 features needed to interpret PDF 1.3 et seq.
2609 
(int.mak [1.33]: 2000/09/07 06:35:06 lpd)
2610 
	- Cleans up some missing and incorrect dependencies.
2611 
(devs.mak [1.33], int.mak [1.34], lib.mak [1.35]: 2000/09/11 04:43:09 lpd)
2612 
	- The definition of PSRCDIR was inconsistent with the definition of
2613 
PVERSION. (openvms.mak [1.5]: 2000/09/22 04:05:40 lpd)
2614 
	- The pgnm and pnm drivers didn't properly detect the presence of
2615 
gray shades or color in images, sometimes causing gray or color information
2616 
to be lost in the output. (fix contributed by a user) (devs.mak [1.35]:
2617 
2000/09/23 04:52:56 lpd)
2618 
 
2619 
Initializes files for the 6.24 fileset. (version.mak [1.19]: 2000/08/09
2620 
16:54:02 lpd)
2621 
 
2622 
Adds a mention of the Color LaserJet 4500 as a color PCL XL printer.
2623 
(devs.mak [1.32]: 2000/08/17 20:43:50 lpd)
2624 
 
2625 
Changes text to make it clear that Yves Arrouye no longer maintains the BJC
2626 
drivers that he wrote. (contrib.mak [1.19]: 2000/08/21 14:38:28 lpd)
2627 
 
2628 
Puts the logic for detecting garbage after %%EOF (and some similar invalid
2629 
constructs) back into the main code, making it produce a message on stderr.
2630 
(unixinst.mak [1.12]: 2000/08/23 02:22:39 lpd)
2631 
 
2632 
Starts to implement the PDF 1.4 transparency features. All API and operator
2633 
additions are now implemented (at least as stubs) and documented, as is
2634 
bookkeeping for the new scalar graphics state members (but not for the soft
2635 
masks or the transparency group stack). (int.mak [1.29], lib.mak [1.30]:
2636 
2000/08/23 21:46:31 lpd)
2637

2639 
(lib.mak [1.31]: 2000/08/24 05:42:30 lpd)
2640 
 
2641 
Partly implements opacity and shape mask bookkeeping. gsave/grestore/etc.
2642 
and banding don't do the right thing yet. (int.mak [1.30],

2646 
self-consistent state. (lib.mak [1.32]: 2000/08/30 01:34:40 lpd)

Starts to implement the PDF 1.4 transparency features. All API and operator
3052 
additions are now implemented (at least as stubs) and documented, as is
3053 
bookkeeping for the new scalar graphics state members (but not for the soft
3054 
masks or the transparency group stack). (ztrans.c [1.1]: 2000/08/23 21:46:31
3055 
lpd)
3056 
 
3057 
Partly implements opacity and shape mask bookkeeping. gsave/grestore/etc.
3058 
and banding don't do the right thing yet. (igstate.h [1.2], ztrans.c [1.3]:
3059 
2000/08/25 01:46:48 lpd)
3060 
 
3061 
Implements some minor improvements to the freelist algorithms that can
3062 
produce nearly a factor of 2 speedup in some allocation-intensive
3063 
situations. (isave.c [1.2]: 2000/08/26 03:21:34 lpd)
3064 
 
3065 
Brings the (still mostly stubbed) transparency code to a more
3066 
self-consistent state. (ztrans.c [1.4]: 2000/08/30 01:34:40 lpd)
3067 
 
3068 
Finishes the code for parsing ImageType 103 (soft-mask) images.
3069 
(ztrans.c [1.5]: 2000/08/30 04:30:06 lpd)
3070 
 
3071 
Completes the parsing of .{begin,end}transparency{group,mask}, except for
3072 
the TransferFunction for masks. The specification is still subject to
3073 
change. (ztrans.c [1.6]: 2000/08/30 15:03:36 lpd)
3074 
 
3075 
*Really* finishes the transparency rendering stack operators (the previous
3076 
version didn't even compile), except for TransferFunction. (ztrans.c [1.7]:
3077 
2000/08/30 21:11:55 lpd)
3078 
 
3079 
Implements another chunk of the PDF 1.4 transparency features, fixing some
3080 
bugs in the previous code. (lib/gs_ll3.ps [1.4], ztrans.c [1.8]: 2000/09/10
3081 
05:26:27 lpd)
3082 
 
3083 
Checks that the TransferFunction of a soft mask is 1-in, 1-out; sets Matted
3084 
correctly in the soft mask parameters passed to the graphics library.
3085 
(ztrans.c [1.9]: 2000/09/11 02:10:28 lpd)
3086 
 
3087 
Moves the Matte entry of soft mask images from the main structure to the
3088 
mask structures, and changes Matted to has_Matte. (ztrans.c [1.10]:
3089 
2000/09/11 04:08:13 lpd)
3090 
 
3091 
Upgrades the proposed driver interface transparency extension from comments
3092 
to macros, changing the name 'discard_transparency_level' to
3093 
'discard_transparency_layer'. (ztrans.c [1.11]: 2000/09/11 20:13:31 lpd)

3281 
(gp.h [1.4], gxfill.c [1.4], gxtext.h [1.2]: 2000/08/31 03:51:29 lpd)
3282 
	- Because "-" as an OutputFile now references the %stdout IODevice,
3283 
it no longer worked in configurations without a PostScript interpreter.
3284 
Fixing this required factoring out the stdin/out/err IODevices and providing
3285 
an implementation that didn't reference the PostScript interpreter.
3286 
(gsiodevs.c [1.1], gslib.c [1.2]: 2000/09/07 06:14:45 lpd)
3287 
	- Fixes a type error caused by a change in the TransferFunction
3288 
member of gs_transparency_mask_params_t. (gstrans.c [1.7]: 2000/09/10
3289 
18:20:09 lpd)
3290 
	- Several places in the code for ImageType 3x (soft-masked) images
3291 
didn't correctly handle the case where only one of the two masks was
3292 
supplied (which is always the case for PDF). (gximag3x.c [1.4]: 2000/09/11
3293 
02:12:19 lpd)
3294 
	- The -Zv tracing messages for gs_begin_transparency_{group,mask}
3295 
were incorrect. (gstrans.c [1.10]: 2000/09/12 20:35:05 lpd)
3296 
	- Printing the program name and version didn't use fprintf, so it
3297 
didn't work properly with the stdout redirection on Windows. (fix from
3298 
Artifex) (gsmisc.c [1.7]: 2000/09/18 06:22:35 lpd)
3299 
	- Undefined characters in CID-keyed (FMapType 9) composite fonts
3300 
caused an infinite loop, because the parsing index was never advanced past
3301 
the character. (gsfcmap.c [1.7]: 2000/09/21 02:44:44 lpd)
3302 
	- CID-keyed (FMapType 9) composite fonts didn't return the correct
3303 
parsed character code, possibly causing widthshow or cshow to produce
3304 
incorrect output. (gsfcmap.c [1.8], gsfcmap.h [1.4]: 2000/09/21 03:02:03

Starts to implement the PDF 1.4 transparency features. All API and operator
3321 
additions are now implemented (at least as stubs) and documented, as is
3322 
bookkeeping for the new scalar graphics state members (but not for the soft

3339 
2000/08/24 19:20:12 lpd)

3352 
 
3353 
Implements some minor improvements to the freelist algorithms that can
3354 
produce nearly a factor of 2 speedup in some allocation-intensive

3366

Completes the parsing of .{begin,end}transparency{group,mask}, except for
3368 
the TransferFunction for masks. The specification is still subject to

mask. (gximag3x.c [1.6]: 2000/09/11 04:38:01 lpd)
3391

Upgrades the proposed driver interface transparency extension from comments

(Drivers)
3613 
	- With high-level drivers ([e]pswrite, pdfwrite, pxl*, cgm*),
3614 
changing the OutputFile after writing one or more pages now causes an error.
3615 
(Interpreter)
3616 
	- By default, copydevice will only copy a device prototype.
3617 
	- Some internal references to contexts in zcontext.c are changed
3618 
from direct pointers to context indices.
3619 
	- Renames internal types to add a _t: ctx_list, ctx_status,
3620 
gs_context, gs_condition, gs_lock.
3621 
(Library)
3622 
	- By default, gs_copydevice[2] will only copy a device prototype.

Fixes problems:
3628 
	- Local GC in a multi-context system caused a crash. Also updates
3629 
all the internal type names in zcontext.c by adding a _t suffix if
3630 
necessary. (doc/News.htm [1.54]: 2000/07/10 23:56:55 lpd)
3631 
	- With some high-level drivers, changing the OutputFile after
3632 
opening the device could cause a crash. After the fix, doing this works
3633 
properly if no pages have actually been written out, but causes a rangecheck
3634 
error if any pages have been written. (This is required to maintain internal
3635 
consistency.) (doc/News.htm [1.55]: 2000/07/12 14:02:03 lpd)
3636 
	- The documented limit on the length of a file name was incorrect.
3637 
(doc/Language.htm [1.9]: 2000/08/03 06:45:25 lpd)
3638

3640 
(doc/News.htm [1.52]: 2000/07/06 02:45:06 lpd)
3641 
 
3642 
Adds a finish_copydevice device procedure, for cleaning up after copying the
3643 
bits of a device prototype or instance. For safety, the default
3644 
implementation only allows copying the prototype, not instances. This is a
3645 
NON-BACKWARD-COMPATIBLE change; however, using copydevice on a device
3646 
instance never worked reliably, so it should not have been used this way
3647 
before. (doc/Drivers.htm [1.4], doc/News.htm [1.53]: 2000/07/06 04:13:24

3666 
close to completing one (referenced from the Ghostscript home page on the

Web). (doc/Projects.htm [1.14]: 2000/07/20 14:49:52 lpd)

	- Removes the '?' procedure, which was defined solely for the
3788 
convenience of users who don't read the documentation and which interfered
3789 
with the operation of some code produced by the Adobe PS5 Windows driver.
3790 
(lib/gs_init.ps [1.18]: 2000/07/09 22:34:30 lpd)
3791 
	- A constant 1 should have been 1L, causing a warning on systems
3792 
where sizeof(long) > sizeof(int). (zarith.c [1.3]: 2000/07/09 23:10:58 lpd)
3793 
	- The workaround for attempting to set a 4-element PageSize value in
3794 
a page device sometimes caused an error. (bug introduced in 6.21)
3795 
(lib/gs_setpd.ps [1.4]: 2000/07/10 12:48:54 lpd)
3796 
	- Redefining setcolorspace could cause an infinite recursion.
3797 
(lib/gs_lev2.ps [1.5]: 2000/07/10 13:35:24 lpd)
3798 
	- Local GC in a multi-context system caused a crash. Also updates
3799 
all the internal type names in zcontext.c by adding a _t suffix if
3800 
necessary. (zcontext.c [1.4]: 2000/07/10 23:56:55 lpd)
3801 
	- A garbage collection occurring within a save could cause a memory
3802 
access error. (bug introduced in 6.22) (zcontext.c [1.5]: 2000/07/14
3803 
05:28:56 lpd)
3804 
	- Piped input beginning with a % caused an ioerror. (bug introduced
3805 
in 6.22) (zfileio.c [1.8]: 2000/07/14 05:30:19 lpd)
3806 
	- A garbage collection occurring while scanning a binary token
3807 
sequence could cause a syntaxerror or corrupted data. (iscan.c [1.3]:
3808 
2000/07/18 15:39:02 lpd)
3809 
	- (correction) An interruption (including a callout for a
3810 
procedure-based stream), not a garbage collection, while scanning a binary
3811 
token sequence could cause a syntaxerror or corrupted data. (iscan.c [1.4]:
3812 
2000/07/18 15:41:55 lpd)
3813 
	- When loading a TrueType font, invalid glyph numbers in the 'post'
3814 
table (which appear in some Adobe-created PDF files) caused an error instead
3815 
of being ignored; a test was backwards, causing some embedded TrueType fonts
3816 
in PDF files to produce a rangecheck error. (lib/gs_ttf.ps [1.6]: 2000/07/19
3817 
08:12:41 lpd)
3818 
	- When NOPROMPT was set, no flush or flushpage occurred at the end
3819 
of a page. (fix from an anonymous user on SourceForge)
3820 
(lib/gs_init.ps [1.19]: 2000/07/20 01:40:50 lpd)
3821 
	- Type 1 or Type 2 fonts with invalid LanguageGroup values < 0
3822 
caused an error. (Such fonts are invalid, but some real fonts have garbage
3823 
LanguageGroup values, and Adobe software doesn't give an error.)
3824 
(zfont1.c [1.6]: 2000/07/24 18:08:38 lpd)
3825 
	- Errors while executing gs_init.ps and other PostScript
3826 
initialization files were sometimes ignored, leading to mysterious error
3827 
messages later. (imainarg.c [1.3]: 2000/08/03 06:43:17 lpd)
3828 
	- Showing text with a singular matrix (scaling matrix x CTM) could
3829 
leave extraneous values on the operand stack. (zchar1.c [1.4]: 2000/08/04
3830 
16:09:30 lpd)

3833 
(lib/gs_init.ps [1.15]: 2000/07/06 02:45:06 lpd)
3834 
 
3835 
Redefines [gs_]copydevice in terms of a new gs_copydevice2/.copydevice2,
3836 
which adds a Boolean keep_open argument that requests (but does not
3837 
guarantee) that a copy of an open device remain open.
3838 
(lib/gs_init.ps [1.16], zdevice.c [1.2]: 2000/07/06 03:26:13 lpd)
3839 
 
3840 
Adds a finish_copydevice device procedure, for cleaning up after copying the
3841 
bits of a device prototype or instance. For safety, the default
3842 
implementation only allows copying the prototype, not instances. This is a
3843 
NON-BACKWARD-COMPATIBLE change; however, using copydevice on a device
3844 
instance never worked reliably, so it should not have been used this way
3845 
before. (lib/gs_init.ps [1.17]: 2000/07/06 04:13:24 lpd)
3846 
 
3847 
Adds the ability to load CIDFont resources from CFF OpenType font files.
3848 
(lib/gs_cff.ps [1.6], lib/gs_cidfn.ps [1.16]: 2000/07/29 05:58:28 lpd)
3849 
 
3850 
Ensures that errordict has at least one empty entry, for the sake of some
3851 
astonishingly bad PostScript code that tests for this and has a bug in the
3852 
case where it isn't true. (lib/gs_init.ps [1.20]: 2000/08/04 04:29:45 lpd)

Fixes problems:
3857 
	- Some coordinate computations for Type 1 fonts could lose far too
3858 
much precision if _fixed_shift was reduced. (gscoord.c [1.2],
3859 
gxmatrix.h [1.2]: 2000/07/11 09:25:46 lpd)

3862 
14:00:09 lpd)
3863 
	- With some high-level drivers, changing the OutputFile after
3864 
opening the device could cause a crash. After the fix, doing this works
3865 
properly if no pages have actually been written out, but causes a rangecheck
3866 
error if any pages have been written. (This is required to maintain internal
3867 
consistency.) (gdevvec.c [1.4]: 2000/07/12 14:02:04 lpd)

distorted characters (e.g., slanted bottoms). (gstype2.c [1.4]: 2000/07/13
3872

<h2><a name="6.22_Incompatible_changes"></a>Incompatible changes</h2>
3949 
 
3950 
(Procedures)
3951 
	- Versions now have odd numbers during development, even numbers
3952 
when released.
3953 
	- The TMPDIR environment variable, if set, now takes precedence
3954 
over TEMP.
3955 
	- On MS-DOS, MS Windows, and OS/2 platforms, the batch files that
3956 
invoke Ghostscript now use a default name of gswin32 or gswin32c rather than
3957 
simply gs.
3958 
(Drivers)
3959 
	- The PCL drivers now select a given paper size if the requested
3960 
height is at least 0.1" greater than the height of the next smaller paper
3961 
size, rather than if the requested height is at least as large as that of
3962 
the given paper size.
3963 
(Interpreter)
3964 
	- user_names_p and system_names_p may now be NULL: clients must
3965 
check this.
3966 
	- scan_comment_proc and scan_dsc_proc are now deprecated, and will
3967 
disappear in the near future.
3968 
	- The values in psuserparams are now checking procedures rather
3969 
than parameter values.
3970 
	- Comments beginning with %! are treated as "DSC comments", like
3971 
comments beginning with %%.
3972 
(Library)
3973 
	- The macro for declaring the fill_rectangle procedure of a shading
3974 
is now upper-case.  The fill_rectangle procedure is now a member of a procs
3975 
structure; there is a new macro for calling it.
3976 
	- The parameter list and return value for gs_currentgray have
3977 
changed.  This is very unfortunate, but it was unavoidable.

Fixes problems:
3983 
	- The batch files for MS-DOS, MS Windows, and OS/2 referred to the
3984 
executable by the name 'gs'. They now use environment variables GS
3985 
(graphical) and GSC (console) for the executable names, defaulting to
3986 
gswin32 and gswin32c respectively. (doc/News.htm [1.45], doc/Use.htm [1.6]:
3987 
2000/05/20 20:53:04 lpd)
3988 
	- The -dCompatibilityLevel= switch was incorrectly identified in one
3989 
place as -dCompatibility=. (doc/Ps2pdf.htm [1.11]: 2000/05/22 21:29:45 lpd)
3990 
	- [gs_]currentgray didn't return the correct value if the current
3991 
color space was a DeviceN space using the alternate space.
3992 
(doc/News.htm [1.49]: 2000/07/03 15:28:26 lpd)

3995 
	- The "smoke test" procedure for fileset releases didn't stress the
3996 
banding code nearly as hard as intended. (doc/Release.htm [1.13]: 2000/07/05

Fixes problems:
4097 
	- The rule for the recently-added gdevhl12 driver omitted the space
4098 
before the colon. (contrib.mak [1.12]: 2000/05/02 01:42:12 lpd)

4100 
(lib.mak [1.19]: 2000/05/02 07:14:11 lpd)
4101 
	- smd5.c didn't compile properly with "traditional C" compilers.
4102 
(lib.mak [1.20]: 2000/05/19 06:08:01 lpd)
4103

4105 
winlib.mak [1.3]: 2000/05/19 17:52:51 lpd)
4106 
	- The definitions of user names weren't properly associated with
4107 
local VM (they were stored in a static variable). (int.mak [1.22]:
4108 
2000/05/26 02:27:58 lpd)
4109 
	- 'make install' on Unix systems didn't install pdfopt.ps and
4110 
pdfwrite.ps. (unixinst.mak [1.11]: 2000/05/30 23:07:34 lpd)
4111

wrong, causing build problems if this driver was included.
4113 
(contrib.mak [1.13]: 2000/06/01 20:25:39 lpd)
4114 
	- The change to implement stripped TIFF files broke non-TIFF fax
4115

4116 
writing. (devs.mak [1.26]: 2000/06/06 06:37:37 lpd)

4118 
2000/06/07 06:36:54 lpd)
4119

4120 
accurate results. (lib.mak [1.23]: 2000/06/20 15:46:53 lpd)
4121

Finishes working around the fact that Microsoft C, in defiance of multiple
4182 
standards, by default doesn't define the O_ flags for 'open' in fcntl.h (or
4183 
anywhere else). (lib.mak [1.25]: 2000/07/05 00:48:21 lpd)

4198 
	- gsdll_init didn't propagate an error return from
4199 
gs_main_init_with_args, causing clients to think Ghostscript was initialized
4200 
properly when it wasn't. (gsdll.c [1.2]: 2000/05/20 14:39:42 lpd)
4201 
	- The batch files for MS-DOS, MS Windows, and OS/2 referred to the
4202 
executable by the name 'gs'. They now use environment variables GS
4203 
(graphical) and GSC (console) for the executable names, defaulting to
4204 
gswin32 and gswin32c respectively. (lib/bdftops.bat [1.2],

4213 
	- The ps2pdf.bat script didn't set the default PDF level, so it
4214 
normally produced PDF 1.3 rather than 1.2, which was contrary to the
4215 
documentation and different from the Unix ps2pdf script.

Fixes problems:
4247 
	- The "compressed data" command encoding was wrong in one place in
4248 
the documentation, and the code used the incorrect encoding.
4249 
(gdevatx.c [1.2]: 2000/05/06 00:31:25 lpd)
4250 
	- If a file made no marks at all, ps2[e]ps produced bad output.
4251 
(gdevps.c [1.8]: 2000/05/07 15:38:27 lpd)
4252 
	- Returning an image compression parameter dictionary didn't close
4253 
an enumeration, failing to free a bookkeeping structure. (gdevpsdp.c [1.5]:
4254 
2000/05/11 16:13:16 lpd)
4255 
	- The epswrite driver could produce output that used initclip, which
4256 
is not allowed in EPS files. (gdevps.c [1.9]: 2000/05/20 06:36:30 lpd)
4257 
	- The change to implement stripped TIFF files broke non-TIFF fax
4258 
output formats (faxg* drivers). Also factors plain-fax writing from TIFF
4259 
writing. (gdevfax.c [1.1], gdevfax.h [1.1], gdevtfax.c [1.3],
4260 
gdevtfax.h [1.3]: 2000/06/06 06:37:37 lpd)
4261 
	- In the X driver, resetting MaxBitmap didn't have the proper
4262 
effect, and could cause a crash. (This is probably only a partial fix.)
4263 
(gdevxini.c [1.4]: 2000/06/12 01:52:16 lpd)

4265 
(gdevxini.c [1.5]: 2000/06/12 02:45:25 lpd)
4266 
	- In the ATX drivers, the word count for compressed scan lines was
4267 
written as 2 bytes rather than 1; the drivers wouldn't accept a page width
4268 
greater than 2400 pixels. (gdevatx.c [1.4]: 2000/06/12 04:39:48 lpd)

Works around the fact that Microsoft Visual C++ defines S_IREAD and S_IWRITE
4639 
but not their newer equivalents S_IRUSR and S_IWUSR. (gpmisc.c [1.2]:

Finishes working around the fact that Microsoft C, in defiance of multiple
4652 
standards, by default doesn't define the O_ flags for 'open' in fcntl.h (or

<h2><a name="6.21_Incompatible_changes"></a>Incompatible changes</h2>
4696 
 
4697 
(Drivers)
4698 
	- The downsampling filters now require WidthIn and HeightIn,
4699 
replacing Columns.
4700 
	- The gp_ procedures for managing screen swapping between console
4701 
and graphics are removed.
4702 
	- Any driver that processes the pdfmark pseudo-parameter must now
4703 
also return null for the "value" of the pdfmark parameter when (and only
4704 
when) specifically requested.
4705 
(PDF writer)
4706 
	- The last argument of pdf_alloc_font has changed.
4707 
	- pdf_set_color is renamed pdf_set_pure_color.
4708 
	- When producing PDF 1.3 output, the base 14 fonts are now
4709 
candidates for embedding just like any other fonts.
4710 
(Interpreter)
4711 
	- The .fontproperties procedure in gs_fonts.ps now takes an
4712 
additional argument.
4713 
	- The interpreter must no longer reference stdin/out/err directly.
4714 
(Library)
4715 
	- The internal representation of CMaps is changed completely, and
4716 
has several new required members.
4717 
	- gs_cmap is renamed gs_cmap_t; gx_code_map is renamed
4718 
gx_code_map_t.
4719 
	- Clients creating CMaps must call gs_cmap_init to initialize them.
4720 
	- The library must no longer reference stdin/out/err directly.

Fixes problems:
4726 
	- The PDF writer could get an ioerror when downsampling images whose
4727 
size wasn't an exact multiple of the downsampling factor.
4728 
(doc/News.htm [1.31]: 2000/04/13 16:44:59 lpd)
4729 
	- When processing a PDF file, the font substitution heuristic based
4730 
on the FontName sometimes overrode the Flags information in the
4731 
FontDescriptor. (doc/News.htm [1.34]: 2000/04/20 06:36:02 lpd)
4732 
	- When pdfwrite was producing PDF 1.3 output, the base 14 fonts were
4733 
never embedded, rather than being handled like all other fonts.
4734 
(doc/News.htm [1.37]: 2000/04/20 23:49:40 lpd)
4735

lib/pdfopt.ps. (unixinst.mak [1.7]: 2000/04/07 19:17:48 lpd)
4877 
	- gsmake would get into a loop if the makefile was not a symbolic
4878

4879 
(toolbin/gsmake.tcl [1.2]: 2000/04/07 19:37:21 lpd)
4880

have worked?) (toolbin/makeset.tcl [1.3]: 2000/04/07 19:39:27 lpd)
4882

4890 
	- `make install' didn't install all the documentation files.
4891 
(unixinst.mak [1.9]: 2000/04/14 04:06:13 lpd)
4892 
	- The Color LaserJet 5 drivers were incorrectly identified as

In anticipation of handling more general colors, renames pdf_set_color as
4926 
pdf_set_pure_color, and adds pdf_set_drawing_color. (devs.mak [1.13]:

Splits off creation and writing of color spaces, and writing color values,
4930 
into a separate file. Adds support for (Function-based) Separation and
4931 
DeviceN color spaces, general Pattern color spaces, and procedure-based
4932 
Indexed color spaces. Adds some code to support Pattern colors, but stubs it
4933 
out because it depends on changes in the image writing code that haven't
4934 
been integrated yet. In fact, most of the new code isn't called yet, either.

5515 
 
5516 
(Procedures)
5517 
	- The default value of FPU_TYPE in all Windows and OS/2 makefiles
5518 
is now 387 rather than 0.
5519 
	- The process for reporting problems has changed significantly.
5520 
(PDF writer)
5521 
	- The Cos procedures no longer take the device as an argument,
5522 
except for object-creating procedures, which now take the device rather
5523 
than an allocator.
5524 
	- The is_object member of Cos values is replaced by value_type.
5525 
Clients must use COS_VALUE_IS_OBJECT() to test whether a value is an object
5526 
reference.
5527 
	- The Cos procedures that take C strings no longer copy the string.
5528 
	- The argument of cos_write_object is no longer const.
5529 
(Drivers)
5530 
	- The default BufferSpace for printer drivers is now 4 Mb.
5531 
	- Device halftone order implementations must now provide a new
5532 
bit_index procedure.
5533 
	- The image argument for psdf_setup_image_filters is changed from
5534 
gs_image_t to gs_pixel_image_t.
5535 
	- The font-related psdf_ procedures are renamed psf_.
5536 
(Streams)
5537 
	- The interface to the [T]BCP filters is now in a separate file,
5538 
sbcp.h.
5539 
(PDF interpreter)
5540 
	- The internal beginpage procedure is renamed dictbeginpage, and
5541 
now takes a dictionary argument.
5542 
(Interpreter)
5543 
	- The argument list for the internal build_gs_TrueType_font
5544 
procedure has changed.
5545 
	- The zcharstring_glyph_outline procedure is renamed
5546 
zchar1_glyph_outline.
5547 
	- The Instances dictionary of resources is renamed .Instances.
5548 
(Library)
5549 
	- ImageType 4 images now give an error if a MaskColor value is out
5550 
of the range of possible sample values.
5551 
	- The definition of gs_param_key_t, the key type returned by
5552 
parameter list enumeration, is changed.
5553 
	- Implementors of parameter lists must now call gs_param_list_init
5554 
to initialize the common members.
5555 
	- st_indexed_map is now private.  Clients allocating instances of
5556 
this structure must now call alloc_indexed_map.
5557 
	- Setting a transfer map as the identity mapping now requires
5558 
calling gx_set_identity_transfer.
5559 
	- gs_cid_system_info is renamed gs_cid_system_info_t.
5560 
	- The get_outline procedure of a Type 42 or Type 11 (CIDFontType 0)
5561 
font now returns 1 if the string was newly allocated and can be freed by the
5562 
client.
5563 
	- The procs member of gs_type1_data is now an in-line structure
5564 
rather than a pointer to a const structure.

5569 
Fixes problems:
5570 
	- If log2_transfer_map_size > 8, identity transfer functions
5571 
returned garbage. The fix requires that if a client wants to set a transfer
5572 
function to the identity mapping, it must call gx_set_identity_transfer
5573 
rather than simply setting the procedure to gs_identity_transfer.
5574 
(doc/News.htm [1.13]: 2000/03/19 17:14:47 lpd)
5575 
	- In PDF files, the page CropBox was not being used to clip the
5576 
output. (doc/News.htm [1.18]: 2000/03/21 23:08:32 lpd)
5577 
	- Fixes several problems in resourceforall and resource loading: the
5578 
operands of resourceforall were restored even in the case of an error in the
5579 
client's procedure; the name Instances had special meaning for some Adobe
5580 
code; resourceforall caused an invalidaccess error if an operand was in
5581 
local VM but the current VM was global; loading a resource from a file could
5582 
cause a typecheck error if the file left values on the operand stack.
5583 
(doc/News.htm [1.25]: 2000/04/04 22:26:02 lpd)
5584 
	- The location of the lists of supported and unsupported drivers was
5585 
incorrect. (doc/Bug-info.htm [1.2]: 2000/04/07 03:01:52 lpd)
5586

5602 
 
5603 
Adds a new document listing projects with which we are seeking help. Also
5604 
makes the description of Changes.htm and News.htm more accurate.
5605 
(doc/New-user.htm [1.2], doc/Projects.htm [1.1], doc/Readme.htm [1.3]:
5606 
2000/03/19 06:07:15 lpd)
5607 
 
5608 
Changes the default value of BufferSpace to 4 Mb. In desktop applications,
5609 
this is a reasonable value that can substantially improve performance
5610 
(especially for color printers); embedded applications will want to set
5611 
BufferSpace themselves in any case. (doc/News.htm [1.9]: 2000/03/19 06:51:13
5612 
lpd)
5613 
 
5614 
Changes the key type returned by parameter list enumeration to include a
5615 
persistence flag, makes C parameter lists support non-persistent keys, and
5616 
upgrades GC descriptors so that parameter lists can be used non-transiently;
5617 
updates implementors of parameter lists to call gs_param_list_init to
5618 
initialize the common members, which is now required. (doc/News.htm [1.10]:
5619 
2000/03/19 15:16:11 lpd)
5620 
 
5621 
Documents the fact that drivers that device halftone order implementations
5622 
must now provide the new bit_index procedure. (This should have been
5623 
documented when bit_index was introduced!) (doc/News.htm [1.11]: 2000/03/19
5624 
15:47:47 lpd)
5625 
 
5626 
Makes st_indexed_map private. Clients must now use the constructor procedure
5627 
alloc_indexed_map rather than allocating instances directly.
5628 
(doc/News.htm [1.12]: 2000/03/19 16:37:28 lpd)
5629 
 
5630 
Update the date and change log for the latest batches of checked-in changes.
5631 
(doc/Changes.htm [1.5]: 2000/03/19 17:29:57 lpd)
5632 
 
5633 
Adds a PDF linearizer ("optimizer"). This is a separate utility (not
5634 
integrated with the pdfwrite driver), written in PostScript.
5635 
(doc/Psfiles.htm [1.2]: 2000/03/20 04:31:22 lpd)
5636 
 
5637 
Adds parsing for the remaining Acrobat Distiller 4 parameters. Implements
5638 
the LockDistillerParams, xxxDownsampleThreshold, xxxImageDict, and
5639 
xxxACSImageDict distiller parameters. Implements DCTEncode as an
5640 
xxxImageFilter option (it used to cause a crash). Makes the
5641 
AutoFilterxxxImages distiller parameters select JPEG encoding (with ACSDict)
5642 
if the image has 8 bits per component and is not Indexed, and LZW/Flate
5643 
otherwise: this still isn't right, but it's closer. Implementation changes:
5644 
Changes the implementation of distiller parameter dictionaries from stream
5645 
states to parameter lists; changes the test for masks in
5646 
psdf_setup_image_filters, and changes the image argument from gs_image_t to
5647 
gs_pixel_image_t. (doc/News.htm [1.14]: 2000/03/20 05:40:04 lpd)
5648 
 
5649 
Moves font-writing support into a new module (gdevpsf*), changing the source
5650 
file names. Adds the ability to write CFF fonts, with either Type 1 or Type
5651 
2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts
5652 
with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to
5653 
Type 2, including optimizing sequences of Type 1 operators into a single
5654 
Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT
5655 
TESTED]. Starts (just barely) to remove more unneeded information from
5656 
embedded TrueType fonts. (doc/News.htm [1.15]: 2000/03/20 07:02:12 lpd)
5657 
 
5658 
Updates the consolidated change log with today's changes.
5659 
(doc/Changes.htm [1.6]: 2000/03/20 07:18:38 lpd)
5660 
 
5661 
Starts to move support for CIDFontType 0 and 2 into C code, needed by the
5662 
PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for
5663 
CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts
5664 
that have a GlyphDirectory (not documented in the PLRM, but clearly
5665 
correct). Implements Adobe 3011 features: integer and dictionary CIDMaps,
5666 
and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code,
5667 
which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.)
5668 
(doc/News.htm [1.16]: 2000/03/20 19:53:06 lpd)
5669 
 
5670 
Notes that the argument list for the internal build_gs_TrueType_font
5671 
procedure has changed, as part of the CIDFont migration to C code.
5672

5673

5682 
 
5683 
Substantially enhances the Cos object machinery. Interface: Adds a few more
5684 
procedures, including a procedure to create a stream that writes directly
5685 
into a Cos stream object, procedures for putting more kinds of values into
5686 
arrays and dictionaries, and a param_list interface. Changes Cos objects to
5687 
store a reference to the PDF device, and removes the device argument from
5688 
all Cos procedures other than object creation. Replaces the Boolean
5689 
is_object member of Cos values by a value_type enum: clients must now use
5690 
COS_VALUE_IS_OBJECT() to test whether a value is an object reference. To
5691 
reduce allocator overhead, makes the Cos procedures that take C strings no
5692 
longer copy the string. Records whether each Cos object has been written
5693 
into the output, so that in the future (but not in this batch of changes)
5694 
resource definitions can be copied at the end of each page. Implementation:
5695 
Moves more of the implementation of Cos objects to the .c file.
5696 
(doc/News.htm [1.19]: 2000/03/24 06:12:52 lpd)
5697 
 
5698 
Adds parsing for the remaining Acrobat Distiller 4 parameters, although most
5699 
of them don't have any effect yet; brings documentation up to date.
5700 
(doc/Ps2pdf.htm [1.3]: 2000/03/28 07:36:58 lpd)
5701 
 
5702 
Implements LockDistillerParams; completes the StartPage/EndPage fix checked

5707 
(doc/News.htm [1.20]: 2000/03/28 17:03:48 lpd)
5708 
 
5709 
Changes the get_outline / glyph_data procedure for getting encoded font
5710 
outline data to return an indication of whether the outline data were just
5711 
allocated and can be freed by the client. (This is a possibly
5712 
non-backward-compatible change.) (doc/News.htm [1.21]: 2000/03/28 18:47:02
5713 
lpd)
5714 
 
5715 
Adds a note about bogus "ANSI aliasing" warnings from the DEC C compiler.
5716 
(doc/Make.htm [1.8]: 2000/03/29 19:29:08 lpd)
5717 
 
5718 
Changes the procs structure of gs_type1_data to an in-line structure rather
5719 
than a pointer to a const structure. (Needed for moving CIDFontType 0
5720 
support into C.) (doc/News.htm [1.22]: 2000/03/29 22:10:31 lpd)

5728 
Finishes implementing the ability to write CIDFontType 0 CFFs. This involved
5729 
a surprising number of changes in other font-related files.

5804 
Starts to move support for CIDFontType 0 and 2 into C code, needed by the
5805 
PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for
5806 
CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts
5807 
that have a GlyphDirectory (not documented in the PLRM, but clearly
5808 
correct). Implements Adobe 3011 features: integer and dictionary CIDMaps,
5809 
and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code,
5810 
which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.)

Substantially enhances the Cos object machinery. Interface: Adds a few more

into a Cos stream object, procedures for putting more kinds of values into

arrays and dictionaries, and a param_list interface. Changes Cos objects to
6035 
store a reference to the PDF device, and removes the device argument from
6036 
all Cos procedures other than object creation. Replaces the Boolean
6037 
is_object member of Cos values by a value_type enum: clients must now use
6038 
COS_VALUE_IS_OBJECT() to test whether a value is an object reference. To
6039 
reduce allocator overhead, makes the Cos procedures that take C strings no
6040 
longer copy the string. Records whether each Cos object has been written

Fixes problems:
6123 
	- Font substitution was broken. (lib/gs_fonts.ps [1.3]: 2000/03/19
6124 
00:22:05 lpd)
6125 
	- The CFF reader gave an error if a font included any Subrs (it's
6126 
very surprising that this hasn't surfaced before, but apparently Acrobat
6127 
Distiller always produces CFF fonts with no Subrs); the CFF reader didn't
6128 
default lenIV to -1 for Type 1 CharStrings; the CFF reader wasn't able to
6129 
read CIDFonts. (lib/gs_cff.ps [1.3], lib/gs_cidfn.ps [1.4]: 2000/03/19
6130 
00:45:40 lpd)
6131 
	- EXTEND_NAMES had stopped working, because not all places that
6132 
needed the index of a name ref used name_index rather than r_size
6133 
(ilocate.c), and because the high_index value in the name sub-table was set
6134 
incorrectly (iname.c). (ilocate.c [1.2], iname.c [1.2]: 2000/03/19 01:33:23
6135 
lpd)
6136 
	- The attribute check for Functions being executed was incorrect
6137 
(always succeeded). (zfunc.c [1.2]: 2000/03/19 02:12:37 lpd)
6138 
	- s_add_filter didn't ensure enough buffering. This entailed moving
6139 
the NullEncode/Decode filters to stream.[hc]. (sfilter1.c [1.2]: 2000/03/19
6140 
03:15:02 lpd)
6141 
	- The parameters of SubFileDecode filters weren't initialized fully
6142 
(required by a change in this version). (zfilter.c [1.3]: 2000/03/19
6143 
04:03:45 lpd)
6144 
	- The AutoPositionEPSFiles Distiller parameter was misspelled
6145 
AutoPositionEPSFile. (lib/gs_pdfwr.ps [1.2]: 2000/03/19 05:03:31 lpd)
6146 
	- Enumerating the elements of a dictionary-based parameter list
6147 
returned garbage for the keys. (iparam.c [1.2]: 2000/03/19 15:13:13 lpd)
6148 
	- .buildfont0 should not check CIDSystemInfo compatibility. The
6149 
PLRM3 says PostScript interpreters do not make this check, even though the
6150 
PLRM2 says compatibility is required (!). (zfcmap.c [1.2]: 2000/03/19
6151 
16:53:50 lpd)
6152 
	- If log2_transfer_map_size > 8, identity transfer functions
6153 
returned garbage. The fix requires that if a client wants to set a transfer
6154 
function to the identity mapping, it must call gx_set_identity_transfer
6155 
rather than simply setting the procedure to gs_identity_transfer.
6156 
(zcolor.c [1.2]: 2000/03/19 17:14:47 lpd)
6157 
	- Separation color spaces didn't store the separation name.
6158 
(zcssepr.c [1.2]: 2000/03/19 17:21:36 lpd)
6159 
	- The addition of the dummy cid_Setup procedure in gs 6.01 was
6160 
accidentally commented out. (lib/gs_cidfn.ps [1.5]: 2000/03/21 00:11:55 lpd)
6161 
	- The test for whether an CIDFontType 2 outline string was large
6162 
enough to include prefixed metrics was backwards, which would have caused
6163 
problems with any font that used MetricsCount. (zfcid.c [1.3]: 2000/03/21
6164 
00:43:17 lpd)
6165 
	- A couple of places in the Windows code didn't correctly handle
6166 
Ghostscript version numbers of the form #.0#. (dwsetup.cpp [1.2]: 2000/03/22
6167 
21:45:03 lpd)
6168 
	- In some cases, re-registering an existing font or CIDFont with
6169 
definefont would cause an invalidfont error. (zbfont.c [1.4],
6170 
zfont42.c [1.3]: 2000/03/28 18:20:39 lpd)
6171 
	- Re-registering a CIDFont with definefont, or defining a CIDFont
6172 
with definefont instead of /CIDFont defineresource, caused an invalidfont
6173 
error or a crash. (lib/gs_cidfn.ps [1.9], lib/gs_fonts.ps [1.4]: 2000/03/28
6174 
18:21:50 lpd)
6175 
	- The new C BuildGlyph code for CIDFontType 0 fonts didn't handle
6176 
GlyphDirectory or Type 2 CharStrings correctly. (lib/gs_cidfn.ps [1.12],
6177 
zfcid.c [1.8]: 2000/03/31 23:21:57 lpd)
6178 
	- The internaldict "operator" was allocated in local VM, preventing
6179 
it from being bound into procedures allocated in global VM.
6180 
(lib/gs_init.ps [1.6]: 2000/04/04 22:16:02 lpd)
6181 
	- If there was a CIDInit ProcSet defined in the filesystem, the code
6182 
for initializing the built-in CIDInit ProcSet became confused.
6183 
(lib/gs_cidfn.ps [1.13]: 2000/04/04 22:17:33 lpd)
6184 
	- Fixes several problems in resourceforall and resource loading: the
6185 
operands of resourceforall were restored even in the case of an error in the
6186 
client's procedure; the name Instances had special meaning for some Adobe
6187 
code; resourceforall caused an invalidaccess error if an operand was in
6188 
local VM but the current VM was global; loading a resource from a file could
6189 
cause a typecheck error if the file left values on the operand stack.
6190 
(interp.c [1.3], lib/gs_ccfnt.ps [1.2], lib/gs_res.ps [1.3]: 2000/04/04
6191 
22:26:02 lpd)
6192 
	- resourceforall didn't enumerate external (loadable) instances, and
6193 
would enumerate an instance twice if it had both a local and a global
6194 
definition. (lib/gs_res.ps [1.4]: 2000/04/05 21:07:02 lpd)
6195 
	- The implementation of resourcestatus wasn't compatible with some
6196 
badly written code in an Adobe font downloader that assumes that the
6197 
implementation of resourcestatus in Generic and Font is the same.
6198 
(lib/gs_res.ps [1.5]: 2000/04/05 21:20:07 lpd)
6199 
	- The just-checked-in fixed for resourceforall didn't work properly
6200 
for the IdiomSet category. (They probably failed for other categories that
6201 
had no instances, but we didn't check this.) (lib/gs_res.ps [1.6]:
6202 
2000/04/05 21:51:43 lpd)
6203 
	- Some Adobe font downloading code assumed that loading a resource
6204 
file would never leave extra values on the stack; our implementation didn't
6205 
ensure this (by popping them if needed). (lib/gs_res.ps [1.8]: 2000/04/06
6206 
04:50:28 lpd)
6207 
	- If an alphabetic font defined and used a .notdef character,
6208 
pdfwrite always converted it to a bitmap. (lib/gs_lgo_e.ps [1.2]: 2000/04/07

(lib/gs_init.ps [1.4]: 2000/03/19 00:27:22 lpd)
6223 
 
6224 
Adds a pseudo-encoding for the CFF StandardStrings that represent
6225 
characters. (lib/gs_cff.ps [1.2], lib/gs_css_e.ps [1.1]: 2000/03/19 00:38:50
6226 
lpd)
6227 
 
6228 
Refactors the code for getting Type 1/2/4 font parameters so it can be used
6229 
for FDArray entries of CIDFontType 0 fonts. (ifont1.h [1.2], zfont1.c [1.2]:
6230 
2000/03/19 02:07:45 lpd)
6231 
 
6232 
Speeds up Function evaluation slightly, by preallocating space for a
6233 
reasonable number of operands and results on the C stack rather than always
6234 
allocating it on the heap. (zfunc.c [1.3]: 2000/03/19 02:16:58 lpd)
6235 
 
6236 
Adds a public procedure for determining whether a PostScript object is a
6237 
Function, and if so, returning the pointer to the gs_function_t structure.
6238 
(ifunc.h [1.2], zfunc.c [1.4]: 2000/03/19 02:22:01 lpd)
6239 
 
6240 
Splits out the [T]BCP filter interface into a separate file. (zfbcp.c [1.2]:
6241 
2000/03/19 02:40:18 lpd)
6242 
 
6243 
Adds a skip_count parameter to the SubFileDecode filter, giving the number
6244 
of initial bytes or records to skip over. (Needed for printing FunctionType
6245 
4 functions, possibly useful for other things.) (sfilter1.c [1.3]:
6246 
2000/03/19 03:20:18 lpd)
6247 
 
6248 
Replaces the implementation of FunctionType 4 functions at the PostScript
6249 
language level with one that uses the new library-based facilities.
6250 
(zdevice2.c [1.2], zfunc4.c [1.2]: 2000/03/19 06:56:23 lpd)
6251 
 
6252 
Changes the key type returned by parameter list enumeration to include a
6253 
persistence flag, makes C parameter lists support non-persistent keys, and
6254 
upgrades GC descriptors so that parameter lists can be used non-transiently;
6255 
updates implementors of parameter lists to call gs_param_list_init to
6256 
initialize the common members, which is now required. (iparam.c [1.3]:
6257 
2000/03/19 15:16:11 lpd)
6258 
 
6259 
Makes Separation and DeviceN color spaces convert their tint transform
6260 
function to a FunctionType 4 Function if possible, for better accuracy and
6261 
to allow writing in PDF files. (lib/gs_lev2.ps [1.2], lib/gs_ll3.ps [1.2]:
6262 
2000/03/19 15:28:34 lpd)
6263 
 
6264 
Makes st_indexed_map private. Clients must now use the constructor procedure
6265 
alloc_indexed_map rather than allocating instances directly.
6266 
(zcsindex.c [1.2]: 2000/03/19 16:37:28 lpd)
6267 
 
6268 
Refactors the code for building fonts so it can be used for FDArray entries
6269 
of CIDFontType 0 fonts. (bfont.h [1.2], zbfont.c [1.2]: 2000/03/19 16:45:47
6270 
lpd)
6271 
 
6272 
Adds a .fileposition operator that will read the position even of
6273 
non-positionable streams, needed for the PDF linearizer. (zfileio.c [1.3]:
6274 
2000/03/20 04:30:49 lpd)
6275 
 
6276 
Starts to move support for CIDFontType 0 and 2 into C code, needed by the
6277 
PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for
6278 
CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts
6279 
that have a GlyphDirectory (not documented in the PLRM, but clearly
6280 
correct). Implements Adobe 3011 features: integer and dictionary CIDMaps,
6281 
and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code,
6282 
which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.)
6283 
(icid.h [1.1], ifont.h [1.2], ifont42.h [1.1], zcid.c [1.2], zfcid.c [1.1],
6284 
zfcmap.c [1.3], zfont42.c [1.2]: 2000/03/20 19:53:06 lpd)
6285 
 
6286 
Hooks the new CIDMap code into the BuildGlyph procedure for CIDFontType 2
6287 
fonts. (Contrary to a previous log comment, MetricsCount is already hooked
6288 
in.) Support for CIDFontType 2 fonts is now implemented entirely in C, as
6289 
for Type 42 fonts. (lib/gs_cidfn.ps [1.6], zfcid.c [1.2]: 2000/03/21
6290 
00:32:15 lpd)
6291 
 
6292 
Extends the C support for CIDFontType 0 fonts to include those with FontType
6293 
2 subfonts in the FDArray (an Adobe 3011 addition, specifically for CFF
6294 
fonts). (ifont2.h [1.1], zfcid.c [1.4], zfont2.c [1.2]: 2000/03/21 07:43:42
6295 
lpd)
6296 
 
6297 
Changes Subr loading for CIDFontType 0 fonts from lazy to immediate, so that
6298 
C code can be guaranteed access to the Subrs. (In every CIDFontType 0 font
6299 
that we have seen, SubrCount is 5, so this has no significant time or space
6300 
cost.) Also adds support for FDBytes > 1 in GlyphDirectory definitions.
6301 
(lib/gs_cidfn.ps [1.7]: 2000/03/21 20:06:44 lpd)
6302 
 
6303 
Splits off the ReusableStreamDecode filter as a separate module, since
6304 
CIDFontType 0 fonts will use it even in LanguageLevels below 3.
6305 
(lib/gs_frsd.ps [1.1], lib/gs_ll3.ps [1.3], zfrsd.c [1.1]: 2000/03/21
6306 
21:34:57 lpd)
6307 
 
6308 
Makes file streams remember the file name, needed for efficiently
6309 
implementing reusable streams. (zfile.c [1.3], zfileio.c [1.4]: 2000/03/23
6310 
02:13:40 lpd)
6311 
 
6312 
Changes the new .filename operator to return true/false rather than causing
6313 
an error; redefines findlibfile in terms of a simpler .libfile operator +
6314 
.filename. (lib/gs_init.ps [1.5], zfile.c [1.4], zfileio.c [1.5]: 2000/03/23
6315 
18:47:17 lpd)
6316 
 
6317 
Finishes implementing the file case of ReusableStreamDecode. This required
6318 
adding the ability to restrict file-reading streams to a subfile.
6319 
(lib/gs_frsd.ps [1.2], sfilter1.c [1.4], zfileio.c [1.6], zfrsd.c [1.2]:

6321 
 
6322 
Changes the implementation of incrementally loaded CIDFontType 0 fonts to
6323 
use a ReusableStreamDecode filter, in anticipation of moving the BuildGlyph
6324 
procedure for these fonts from PostScript to C. (lib/gs_cidfn.ps [1.8],
6325 
zbfont.c [1.3], zfcid.c [1.5]: 2000/03/27 16:36:24 lpd)
6326 
 
6327 
Changes the get_outline / glyph_data procedure for getting encoded font
6328 
outline data to return an indication of whether the outline data were just
6329 
allocated and can be freed by the client. (This is a possibly
6330 
non-backward-compatible change.) (zfcid.c [1.6]: 2000/03/28 18:47:02 lpd)
6331 
 
6332 
Changes the procs structure of gs_type1_data to an in-line structure rather
6333 
than a pointer to a const structure. (Needed for moving CIDFontType 0
6334 
support into C.) (zfont1.c [1.3]: 2000/03/29 22:10:31 lpd)

6336 
Finishes moving support for CIDFontType 0 fonts from PostScript to C.

Allows dictionaries as the value of CIDMap resources. (Also removes an

unrelated obsolete comment.) (lib/gs_cidfn.ps [1.11]: 2000/03/31 05:11:30
6342 
lpd)
6343 
 
6344 
Finishes implementing the ability to write CIDFontType 0 CFFs. This involved
6345 
a surprising number of changes in other font-related files. (ichar1.h [1.2],
6346 
ifcid.h [1.1], zchar1.c [1.2], zfcid.c [1.9], zfcid0.c [1.1],

zfcid1.c [1.1], zfont1.c [1.4]: 2000/04/02 07:38:46 lpd)
6348 
 
6349 
Makes the .writefont9 operator (used only for testing) available in both
6350 
DEBUG and PROFILE configurations. (zfcid0.c [1.2]: 2000/04/03 02:37:55 lpd)
6351

Extends .forceput to handle arrays as well as dictionaries, required to fix

a bug with internaldict. (zdict.c [1.2], zgeneric.c [1.2]: 2000/04/04
6354 
22:13:23 lpd)
6355 
 
6356 
Works around an Adobe code assumption that the default FindResource
6357

Implements the framework for superexec (but none of the actual access check

(siscale.c [1.2]: 2000/03/29 20:34:45 lpd)
6378 
	- Fixes a couple of typos in the recently checked-in image
6379 
interpolation fix. (siscale.c [1.3]: 2000/03/30 06:55:26 lpd)
6380 
 
6381 
Splits out the [T]BCP filter interface into a separate file. (sbcp.c [1.2],
6382 
sbcp.h [1.1], sfilter.h [1.2]: 2000/03/19 02:40:18 lpd)
6383 
 
6384 
Adds a skip_count parameter to the SubFileDecode filter, giving the number
6385 
of initial bytes or records to skip over. (Needed for printing FunctionType
6386 
4 functions, possibly useful for other things.) (sfilter.h [1.4]: 2000/03/19
6387 
03:20:18 lpd)
6388 
 
6389 
Changes the key type returned by parameter list enumeration to include a
6390 
persistence flag, makes C parameter lists support non-persistent keys, and
6391 
upgrades GC descriptors so that parameter lists can be used non-transiently;
6392 
updates implementors of parameter lists to call gs_param_list_init to
6393 
initialize the common members, which is now required. (spsdf.c [1.2]:
6394 
2000/03/19 15:16:11 lpd)
6395 
 
6396 
Makes file streams remember the file name, needed for efficiently
6397 
implementing reusable streams. (stream.c [1.4], stream.h [1.4]: 2000/03/23
6398 
02:13:40 lpd)
6399 
 
6400 
Finishes implementing the file case of ReusableStreamDecode. This required
6401 
adding the ability to restrict file-reading streams to a subfile.
6402 
(sfxfd.c [1.2], sfxstdio.c [1.2], stream.c [1.5], stream.h [1.5]: 2000/03/24
6403 
03:59:42 lpd)
6404 
 
6405 
Changes a few initializations to suppress warnings from one picky compiler
6406 
that doesn't like ptr = buf - 1 where buf is an array. (spsdf.c [1.3]:
6407

6411 
Fixes problems:
6412 
	- Two comments in the file were incorrect. (gsiparm3.h [1.2]:
6413 
2000/03/19 02:46:11 lpd)
6414 
	- param_coerce_typed, which works with any parameter list
6415 
implementation, was incorrectly described as associated with the default
6416 
implementation. (gsparam.h [1.2]: 2000/03/19 03:37:08 lpd)
6417 
	- TrueType fonts didn't use vhea/vmtx if WMode = 1. Also makes
6418 
gs_font_type42 subclassable, for implementing CIDFontType 2 fonts, and makes
6419 
its procedure for getting a glyph's side bearing and width virtual, required
6420 
to support MetricsCount in CIDFontType 2 fonts. (gstype42.c [1.3],
6421 
gxfont42.h [1.2]: 2000/03/19 03:58:51 lpd)
6422 
	- ImageType 4 images didn't give an error for out-of-range MaskColor
6423 
values. The file also had an unnecessary #include. (gximage4.c [1.2]:
6424 
2000/03/19 04:10:09 lpd)
6425 
	- If log2_transfer_map_size > 8, identity transfer functions
6426 
returned garbage. The fix requires that if a client wants to set a transfer
6427 
function to the identity mapping, it must call gx_set_identity_transfer
6428 
rather than simply setting the procedure to gs_identity_transfer.
6429 
(gxclrast.c [1.3], gxcmap.c [1.2], gxfmap.h [1.2]: 2000/03/19 17:14:47 lpd)
6430 
	- Fixes a warning about aliasing produced by one extremely picky
6431 
compiler. (gsnogc.c [1.2]: 2000/03/22 21:39:32 lpd)
6432 
	- Filling or clipping with ridiculously large (out-of-bounds)
6433 
coordinates could cause an internal overflow that produced incorrect
6434 
results. (This is probably not the last such bug.) (gxfill.c [1.2]:
6435 
2000/03/30 07:03:59 lpd)
6436 
 
6437 
Provides a gs_atan2_degrees procedure to parallel sin and cos.
6438 
(gsmisc.c [1.2], gxfarith.h [1.2]: 2000/03/18 23:10:39 lpd)
6439 
 
6440 
Improves the 8x8 bitmap "flipping" procedure to take advantage of 32-bit
6441 
ints. (gsutil.c [1.2]: 2000/03/18 23:16:16 lpd)
6442 
 
6443 
Adds a public procedure for restricting a color to its legal range.
6444 
(gscspace.c [1.2], gscspace.h [1.2], gxcspace.h [1.2]: 2000/03/18 23:19:17
6445

6446 
 
6447 
Adds the new ImagemaskTrapping parameter to the trapping state.
6448 
(gstrap.c [1.2], gstrap.h [1.2]: 2000/03/18 23:26:17 lpd)
6449 
 
6450 
Increments the version number to 6.20, in anticipation of the next release.
6451 
(We do this at the beginning of the development for a release, not the end.)
6452 
(gscdef.c [1.2]: 2000/03/19 00:27:22 lpd)
6453 
 
6454 
Adds a pseudo-encoding for the CFF StandardStrings that represent
6455 
characters. (gsccode.h [1.2]: 2000/03/19 00:38:50 lpd)
6456 
 
6457 
Adds a bit_index procedure to the implementation of device halftones,
6458 
required for writing halftones in PDF files. (The only implementors are
6459 
internal ones.) (gxdht.h [1.2], gxhtbit.c [1.2]: 2000/03/19 05:10:55 lpd)
6460 
 
6461 
Adds a public procedure for getting a palette entry of an Indexed color
6462 
space, used when writing Indexed color spaces in PDF files.
6463 
(gscindex.h [1.1], gscolor2.c [1.2], gscolor2.h [1.2]: 2000/03/19 05:20:28
6464 
lpd)
6465 
 
6466 
Reimplements "PostScript calculator" (FunctionType 4) functions entirely in
6467 
C, to allow them to be written out in PDF files. (gsfunc4.c [1.1],
6468 
gsfunc4.h [1.1], gsstruct.h [1.2]: 2000/03/19 05:25:53 lpd)
6469 
 
6470 
Moves gx_device_color_equal to the public API, for detecting redundant color
6471 
setting when writing PDF files. (gsdcolor.h [1.2], gxdcolor.c [1.2],
6472 
gxdcolor.h [1.2]: 2000/03/19 06:46:08 lpd)
6473 
 
6474 
Changes the default value of BufferSpace to 4 Mb. In desktop applications,
6475 
this is a reasonable value that can substantially improve performance
6476 
(especially for color printers); embedded applications will want to set
6477 
BufferSpace themselves in any case. (gdevprn.h [1.2]: 2000/03/19 06:51:13
6478 
lpd)
6479 
 
6480 
Adds virtual procedures for Functions to write their parameters to a
6481 
parameter list, and to access their data source and subfunctions. This is
6482 
needed for writing Functions in PDF files. This change is also a
6483 
prerequisite for the C implemention of FunctionType 4 functions, even though
6484 
it appears later in the change log. (gsdsrc.h [1.2], gsfunc.c [1.2],
6485 
gsfunc.h [1.2], gsfunc0.c [1.2], gsfunc3.c [1.2], gsparam.c [1.2],
6486 
gsparam.h [1.3], gxfunc.h [1.2]: 2000/03/19 07:24:53 lpd)
6487 
 
6488 
Splits off "vanilla" Functions into separate files, in anticipation of
6489 
removing them (they were only used to implement PostScript Calculator
6490 
Functions). (gsfunc.c [1.3], gsfunc.h [1.3], gsfuncv.c [1.1],
6491 
gsfuncv.h [1.1]: 2000/03/19 07:33:08 lpd)
6492 
 
6493 
Adds a procedure for allocating a C parameter list. (gscparam.c [1.2],
6494 
gsparam.h [1.4]: 2000/03/19 15:00:05 lpd)
6495 
 
6496 
Undoes a premature change that depends on an update not yet checked in.
6497 
(gscparam.c [1.3]: 2000/03/19 15:07:59 lpd)
6498 
 
6499 
Changes the key type returned by parameter list enumeration to include a
6500 
persistence flag, makes C parameter lists support non-persistent keys, and
6501 
upgrades GC descriptors so that parameter lists can be used non-transiently;
6502 
updates implementors of parameter lists to call gs_param_list_init to
6503 
initialize the common members, which is now required. (gscparam.c [1.4],
6504 
gsparam.c [1.3], gsparam.h [1.5]: 2000/03/19 15:16:11 lpd)
6505 
 
6506 
Adds a procedure for copying one parameter list to another.
6507 
(gsparamx.c [1.2], gsparamx.h [1.2]: 2000/03/19 15:35:31 lpd)
6508 
 
6509 
Records the CTM used for sampling HalftoneType 1 spot functions. This is
6510 
needed for recognizing the standard spot functions when producing PDF
6511 
output. Also factors the code for initializing spot functions for the
6512 
benefit of the PDF writer. (gshtscr.c [1.2], gxdht.h [1.3], gzht.h [1.2]:
6513 
2000/03/19 15:43:36 lpd)
6514 
 
6515 
Adds a proc_data member to the map for Separation and Indexed color spaces.
6516 
(gscolor2.c [1.3], gxcolor2.h [1.2]: 2000/03/19 16:23:46 lpd)
6517 
 
6518 
Makes st_indexed_map private. Clients must now use the constructor procedure
6519 
alloc_indexed_map rather than allocating instances directly.
6520 
(gscolor2.c [1.4], gscsepr.c [1.2], gxclrast.c [1.2], gxcolor2.h [1.3]:
6521 
2000/03/19 16:37:28 lpd)
6522 
 
6523 
Adds procedures for building and accessing DeviceN color spaces.
6524 
(gscdevn.c [1.2], gscdevn.h [1.1]: 2000/03/19 17:02:37 lpd)
6525 
 
6526 
Exports the 'blend' operators of the Type 1 interpreter, for use by the Type
6527 
1 / Type 2 font writer. (gstype1.c [1.3], gxtype1.c [1.2], gxtype1.h [1.3]:
6528 
2000/03/19 18:46:44 lpd)
6529 
 
6530 
Starts to move support for CIDFontType 0 and 2 fonts into C code. (These
6531 
header files are the ones needed to compile the new gdevpsf* files; they
6532 
don't interact with any existing code.) (gxcid.h [1.1], gxfcid.h [1.1]:
6533 
2000/03/20 06:40:22 lpd)
6534 
 
6535 
Moves font-writing support into a new module (gdevpsf*), changing the source
6536 
file names. Adds the ability to write CFF fonts, with either Type 1 or Type
6537 
2 CharStrings; unfortunately, Acrobat Reader appears not to accept CFF fonts
6538 
with Type 1 CharStrings. Adds the ability to convert Type 1 CharStrings to
6539 
Type 2, including optimizing sequences of Type 1 operators into a single
6540 
Type 2 operator. Implements writing CIDFontType 0 CFF fonts (CIDFonts) [NOT
6541 
TESTED]. Starts (just barely) to remove more unneeded information from
6542 
embedded TrueType fonts. (gxttf.h [1.1]: 2000/03/20 07:02:12 lpd)
6543 
 
6544 
Starts to move support for CIDFontType 0 and 2 into C code, needed by the
6545 
PDF writer for handling CID-keyed fonts. Implements GlyphDirectory for
6546 
CIDFonts. Makes GDBytes and CIDMapOffset optional for CIDFontType 0 fonts
6547 
that have a GlyphDirectory (not documented in the PLRM, but clearly
6548 
correct). Implements Adobe 3011 features: integer and dictionary CIDMaps,
6549 
and the MetricsCount entry, in CIDFontType 2 fonts (but only in the C code,
6550 
which isn't hooked in yet, not in the PostScript code in gs_cidfn.ps.)

that doesn't like ptr = buf - 1 where buf is an array. (gxclpath.c [1.2]:
6556 
2000/03/28 02:01:34 lpd)
6557 
 
6558 
Changes the get_outline / glyph_data procedure for getting encoded font
6559 
outline data to return an indication of whether the outline data were just
6560 
allocated and can be freed by the client. (This is a possibly
6561 
non-backward-compatible change.) (gxfcid.h [1.2], gxfont42.h [1.3]:
6562 
2000/03/28 18:47:02 lpd)
6563 
 
6564 
Changes the procs structure of gs_type1_data to an in-line structure rather
6565 
than a pointer to a const structure. (Needed for moving CIDFontType 0
6566 
support into C.) (gstype1.c [1.4], gstype2.c [1.3], gxfont1.h [1.3],
6567 
gxtype1.c [1.3]: 2000/03/29 22:10:31 lpd)

Finishes moving support for CIDFontType 0 fonts from PostScript to C.
6570 
(gxfcid.h [1.3]: 2000/03/31 04:55:18 lpd)
6571 
 
6572 
Finishes implementing the ability to write CIDFontType 0 CFFs. This involved
6573 
a surprising number of changes in other font-related files. (gsfcid.c [1.2],

6670 
 
6671 
Adds the ability to set the ProcessColorModel of the pdfwrite device to
6672

error message. (This is a 'fix' of a 'fix' of a 'fix': it might well break
6944 
something else.) (lib/gs_type1.ps [1.2]: 2000/03/10 03:37:14 lpd)
6945 
	- When reading the strings of a binary object sequence, having to
6946 
get more data from a procedure-based stream sometimes caused a syntaxerror.
6947 
Fix: If the reserved (0) field in binary objects or binary object sequences
6948 
was not 0, no syntaxerror occurred. (iscanbin.c [1.2]: 2000/03/10 03:38:50
6949 
lpd)
6950 
	- The code for handling execstackoverflow errors didn't cut back the
6951 
stack correctly, possibly causing invalid memory accesses if an incorrect
6952 
attempt was made to run a cleanup procedure. (interp.c [1.2]: 2000/03/10
6953 
04:04:38 lpd)
6954 
	- Writing of dictionaries in binary object output, a non-standard
6955 
extension, was enabled by default, and also had to be enabled at startup
6956 
time if it was ever going to be used. Fix: Binary error messages caused an
6957 
error if the command wasn't of a type that printobject could handle. We now
6958 
do what the Adobe implementations appear to do in this case, namely, convert
6959 
the object with cvs. (lib/gs_btokn.ps [1.2]: 2000/03/10 04:27:31 lpd)
6960 
	- CloseSource and CloseTarget were effectively ignored for Flate and
6961 
LZW filters with a Predictor, and for the DCT filters. (ifilter.h [1.2],
6962 
zfdctd.c [1.2], zfdcte.c [1.2], zfdecode.c [1.2], zfilter.c [1.2],
6963 
zfilter2.c [1.2]: 2000/03/10 04:32:51 lpd)

	- findlibfile didn't handle %iodevice% prefixes correctly.
6965 
(zfile.c [1.2]: 2000/03/10 04:35:08 lpd)
6966 
	- fileposition didn't give an error for filters or non-seekable
6967 
streams. (zfileio.c [1.2]: 2000/03/10 04:35:53 lpd)
6968 
	- Images with input from a file or filter demanded 1 byte of data
6969 
too many, sometimes causing the last line of the image to be dropped. (bug
6970 
probably introduced in 6.0) (zimage.c [1.2]: 2000/03/10 04:37:02 lpd)
6971 
	- The check for a show within a cshow procedure for a CID font was
6972 
wrong. Fix: Character widths in CIDFontType 0 fonts were ignored (!). Adds a
6973 
.glyphwidth operator to support correct handling of character widths for CID
6974 
fonts. Adds a glyphwidth procedure to the library, like glyphshow and
6975 
glyphpath, in order to support correct handling of widths for CID fonts.

6978 
	- resourcestatus for fonts was broken. (lib/gs_res.ps [1.2]:

6980 
	- Fixes incorrect documentation of several procedures.
6981 
(lib/gs_fonts.ps [1.2]: 2000/03/10 07:00:28 lpd)
6982 
	- The %ram% IODevice was defined, but should not be (it represents a
6983 
RAM-based file system, which Ghostscript does not provide). Fix: The type of
6984 
the %null% IODevice was /FileSystem rather than /Special. (ziodev2.c [1.2]:
6985 
2000/03/10 07:02:07 lpd)
6986 
	- Directly-loaded TrueType fonts (including embedded TrueType fonts
6987 
in PDF files) could get confused with each other in the cache, because their
6988 
XUIDs were based on the font checksum field, which some fonts don't have set
6989 
correctly. (lib/gs_ttf.ps [1.3]: 2000/03/16 07:38:07 lpd)
6990 
 
6991 
Adds a new example file, a 3-D synthetic image. (examples/doretree.ps [1.1]:
6992 
2000/03/10 04:00:45 lpd)
6993 
 
6994 
Adds implementations of the devforall, devstatus, and diskonline
6995 
compatibility operators. (lib/gs_statd.ps [1.2]: 2000/03/10 04:01:55 lpd)
6996 
 
6997 
Some Adobe CIDFonts include a line /Setup /cid_Setup load def that
6998 
apparently is intended only to prevent the fonts from being loaded by a
6999 
standard PostScript interpreter (as opposed to ATM or a special font
7000 
loader), since cid_Setup is not defined anywhere and Setup is never
7001 
referenced; this change adds a dummy definition of cid_Setup to work around
7002 
this. (lib/gs_cidfn.ps [1.3]: 2000/03/10 04:53:25 lpd)
7003 
 
7004 
Updates the version # to 6.01, and the version date. (lib/gs_init.ps [1.2]:
7005 
2000/03/10 17:18:29 lpd)
7006 
 
7007 
Changes the default undercolor removal and black generation functions back
7008 
from f(k) = k to f(k) = 0. This fixes some, but not all, of the reported
7009 
problems with color inkjet output in 6.0. (lib/gs_init.ps [1.3]: 2000/03/10
7010 
18:47:31 lpd)
7011 
 
7012 
On Windows, puts stdout into binary mode as well as stdin, to allow piping
7013 
printer output through stdout (not a good idea, but it should be supported
7014 
as well as on other platforms). (dwmainc.cpp [1.2]: 2000/03/17 06:22:59 lpd)

Changes the sbuf_min_left macro to a procedure for readability and in

preparation for later revision. (stream.c [1.2], stream.h [1.2]: 2000/03/10

Fixes problems:
7025 
	- (%os%) currentdevparams didn't return (fixed) values for
7026 
InitializeAction, Mounted, Removable, Searchable, SearchOrder, and
7027 
Writeable, or (meaningful) values for BlockSize, Free, and LogicalSize.
7028 
Currently, the latter values are dummies. (gsiodev.c [1.2]: 2000/03/10

7030 
	- The terminating $ on the $Id: line in gsmalloc.c was missing, and
7031 
dwuninst.rc lacked a $Id: line. (gsmalloc.c [1.2]: 2000/03/10 03:44:33 lpd)
7032 
	- RasterOps with source transparency = 0, texture transparency = 1
7033 
didn't match the (very peculiar) H-P specification even if
7034 
TRANSPARENCY_PER_H_P was defined. (gdevdrop.c [1.2], gdevmrop.h [1.2],
7035 
gsropt.h [1.2]: 2000/03/10 04:06:15 lpd)
7036 
	- The prototype for gs_exit() was not included even though gs_exit()
7037 
was called. Fix: A cast discarded const unnecessarily. (gsalloc.c [1.2]:
7038 
2000/03/10 04:08:23 lpd)
7039 
	- The type of the %pipe% IODevice was /FileSystem, whereas it should
7040 
be /Special. (gdevpipe.c [1.2]: 2000/03/10 04:13:57 lpd)
7041 
	- An incorrectly formatted procedure couldn't be converted correctly
7042 
by ansi2knr. (gxidata.c [1.2]: 2000/03/10 04:30:58 lpd)
7043 
	- The check for a show within a cshow procedure for a CID font was
7044 
wrong. Fix: Character widths in CIDFontType 0 fonts were ignored (!). Adds a
7045 
.glyphwidth operator to support correct handling of character widths for CID
7046

7049

7050 
	- The description of the value returned by code_map_decode_next in
7051 
*pchr was incorrect. (documentation bug only) (gsfcmap.c [1.2]: 2000/03/10
7052 
07:03:09 lpd)
7053 
	- Fixes a problem producing too much black in the output; also adds
7054 
support for 5 new printers (H-P Color DeskJet 690, H-P DesignJet 750, and
7055 
Epson Stylus Color 200). Note that this is user-contributed code.
7056 
(gsargs.h [1.2]: 2000/03/16 02:01:36 lpd)
7057 
	- The code for Axial shadings incorrectly assumed that if the
7058 
shading axis was horizontal or vertical in user space, it was also
7059 
horizontal or vertical in device space: this caused incorrect results when
7060 
the CTM wasn't orthogonal. (gxshade1.c [1.2]: 2000/03/17 08:17:55 lpd)
7061 
	- For printer devices, a non-null definition for OutputFile was
7062 
required even on platforms that had a default printer (as implemented by
7063 
gp_open_printer for that platform). (gp.h [1.2], gsdevice.c [1.2]:

incrementally. (gstype42.c [1.2]: 2000/03/10 03:45:29 lpd)

7154 
	- There were signed/unsigned char mismatches.  (genht.c, geninit.c)
7155 
	- The MacOS compiler imposes a 32K limit on the size of a stack
7156 
frame: we changed the code to use malloc/free.  (geninit.c)

7163 
Enhances the prfont.ps utility to print CIDFonts.  (lib/prfont.ps)

introduced in 5.99) (gsimage.h, gsimage.c)
7271 
	- ImageType 3 images with unequal scaling for the mask and data
7272 
didn't work.  (We thought they once did, but it appears they never have.)
7273 
(gximage3.c)
7274 
	- Images with 12-bit samples treated a Decode entry of [1 0] the
7275 
same as [0 1].  (Other, general Decode entries worked correctly.)
7276 
(gxipixel.c)
7277 
	- ImageType 3 images didn't work if processing was ever interrupted
7278 
for remapping a color.  (gximage3.c)
7279 
	- Images in DeviceN color spaces with 12-bit samples didn't work.
7280 
(gxi12bit.c, gxidata.c)
7281 
	- Images in DeviceN color spaces could fail to render properly
7282 
because the interruption of rendering left a half-built entry in an internal
7283 
cache.  (gxi12bit.c, gxicolor.c)
7284 
	- Images with non-idempotent RasterOps in 1-component DeviceN color
7285 
spaces didn't render properly, because the same pixel was rendered multiple
7286 
times after a color remapping interruption.  (gximono.c)
7287 
	- The fast case of masked images caused a crash if invoked without
7288 
an imager state.  (gximono.c)
7289 
	- Flushing buffered image data could cause coordinate bookkeeping
7290 
to get out of sync.  (gxidata.c)
7291 
	- ImageType 3, InterleaveType 2 images sometimes failed to render
7292 
the last row.  (gximage3.c)
7293 
	- The fix in 5.88 for resizing large objects had a bug itself.
7294 
(gsalloc.c)
7295 
	- Whan banding, if a client supplied more data than necessary for an
7296 
image, the client was told (incorrectly) that all of the data was used.
7297 
(fix from Artifex) (gxclimag.c)
7298 
	- Null patterns caused a crash. (bug probably introduced by changes
7299 
to support PatternType 2) (gspcolor.c)
7300 
	- On hand-initialized memory devices where line_ptrs[0] != base,
7301 
monobit RasterOps could cause invalid or stray memory accesses.  (gdevmr1.c)
7302 
 
7303 
Removes an unnecessary variable.  (gdevppla.c, gsfont.c)
7304 
 
7305 
Adds the ability to call a specified procedure when unregistering
7306 
notification, needed for removing PDF font registrations.  (gsnotify.h,
7307 
gsnotify.c)
7308 
 
7309 
Updates the copyright year.  (gscdef.c)
